Floating Bowling Balls | Science Experiment

The 8-pound ball displaces 8 pounds of water. However, the ball also takes up more volume than 8 pounds of water, so it floats. The same principle explains why an aircraft carrier floats even though it's made of steel. If you consider that steel has a density of 7.8 g/cm 3, shouldn't the aircraft carrier sink? The ability of the ship to ...

How to round metal edges | The easiest way to make the ...

Good and accurate rounding of steel constructions according to EN 1090, ISO 12944, ISO 8501 or IMO PSPC is becoming more and more important in the metal working industry. Rounding edges with minium radius 2 mm is a necessity for good adhesion of coating or paint to protect against corrosion.

How to Calculate Viscosity | Powerblanket Heating Solutions

Find the radius of the ball by first measuring the diameter (distance of a straight line through the ball at the widest part). Divide the diameter by 2; this gives the radius of your ball. Calculate the volume of the ball by plugging the radius into the equation for the volume of a sphere. Suppose the ball bearing has a radius of 0.01 meter (m).
